We aimed to describe the manometric findings in this subset of patients.A retrospective review of charts between 2013 and 2023 at a tertiary pediatric gastroenterology center, treating roughly 1500 EoE patients per year. We included children with EoE referred to high‐resolution impedance manometry (HRIM) for persistent dysphagia despite histologic healing (i.e., <15 Eos/hpf). Data including initial EoE diagnosis, endoscopy reports, esophageal biopsies, treatment regimens, and HRIM were retrospectively collected.The estimated prevalence of post‐remission dysphagia in our cohort was exceedingly rare (<0.05%). Four patients met the eligibility criteria of histologic remission and absence of fibro‐stenotic features on endoscopic evaluation and thus, were included in this case series. Patients achieved remission with steroids, proton‐pump inhibitor, or both within a median time of 5 months from diagnosis. Peak Eosinophil count at remission was ≤5 Eos/hpf in three patients and ≤10 Eos/hpf in one. On HRIM, all four patients had a hypomotile esophagus and abnormal bolus clearance. Lower esophageal sphincter integrated relaxation pressure values were normal in three patients and elevated in one. Two patients were diagnosed with ineffective esophageal motility, one with aperistalsis and one with achalasia type 1.Post‐remission dysphagia is rare in EoE. Esophageal dysmotility with a hypomotile pattern may contribute to the persistent dysphagia in children with EoE. HRIM should be considered in patients with EoE in whom symptoms persist despite histologic remission.","PeriodicalId":501015,"journal":{"name":"JPGN reports","volume":"43 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141109540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pediatric gastroenterology providers are uniquely equipped to help guide families experiencing this challenge given their specialized training in nutritional support and dietary therapy for disease management. Hence, this study aimed to evaluate food insecurity screening practices from the perspectives of patient caregivers and healthcare providers in a tertiary pediatric gastroenterology practice. A survey was administered to 1279 caregivers and 121 providers. Of the 248 completed caregiver responses, 10%−15% reported being asked about food insecurity. Among the 36 healthcare provider responses, 53% expressed comfort in conducting food insecurity screening but only 14% routinely screened. The most cited barrier to screening was the lack of readily available patient resources. Further research is imperative to address these screening barriers and assess the impact of food insecurity screening and interventions on pediatric gastrointestinal health outcomes.","PeriodicalId":501015,"journal":{"name":"JPGN reports","volume":"1 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140430335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
